The orientation number of three complete graphs with linkages
(Işık University Press, 2021)For a graph G, let D(G) be the set of all strong orientations of G. The orientation number of G is d~(G) = min{d(D)|D ? D(G)}, where d(D) denotes the diameter of the digraph D. In this paper, we consider the problem of ... -
A note on indices of primepower and semiprime divisor function graph
(Işık University Press, 2021)The notion of using number theortic based graph seems to be one of the flourishing areas in Graph theory. One such concept is the divisor function graph GD(n) which is defined as: For any positive integer n ? 1 with r ... -
Fuzzy zero divisor graph in a commutative ring
(Işık University Press, 2021)Let R be a commutative ring and let ?(Zn) be the zero divisor graph of a commutative ring R, whose vertices are non-zero zero divisors of Zn, and such that the two vertices u, v are adjacent if n divides uv. In this paper, ... -
Results on majority dom-chromatic sets of a graph
(Işık University Press, 2021)A majority dominating set S ? V (G) is said to be majority dominating chromatic set if S satisfies the condition ?(hSi) = ?(G). The majority dom-chromatic number ?M?(G) is the minimum cardinality of majority dominating ... -
Cyclic orthogonal double covers of 6-regular circulant graphs by disconnected forests
(Işık University Press, 2021)An orthogonal double cover (ODC) of a graph H is a collection G = {Gv : v ? V (H)} of |V (H)| subgraphs of H such that every edge of H is contained in exactly two members of G and for any two members Gu and Gv in G, |E(Gu) ... -
Integral inequalities via log m-convex functions
(Işık University Press, 2020)In this paper, we introduce and investigate a new concept of log m-convex functions. We establish some new Hermite-Hadamard type integral inequalities via log m-convex functions. Our results represent refinement and ... -
Starlike symmetrical functions
(Işık University Press, 2020)The objective of the present paper is to study subclass S ? ?? ?? (A, B) of analytic functions that is defined by using the class of Janowski functions combined with the (j, k)-symmetrical functions. This class generalizes ... -
Estimation of the location and scale parameters of moyal distribution
(Işık University Press, 2020)In this study, we estimate the parameters of the Moyal distribution by using well-known and widely-used maximum likelihood (ML) and method of moments (MoM) methodologies. The ML estimators of the location and scale parameters ... -
An integral equation involving Saigo-Maeda operator
(Işık University Press, 2020)The aim of this paper is to obtain a solution of integral equation of the Saigo- Maeda operator which contain Appell-hypergeometric function as a kernel. The integral equation and its solution gives new form of generalised ... -
Generalized fixed point results with multi-valued mappings
(Işık University Press, 2020)In this article we deduce fixed point results for multi-valued contraction mappings. We primarily established two fixed results. One of them is the generalization of Nadler’s contraction and the other result is the ... -
Fuzzy parameterized fuzzy soft matrices and their application in decision-making
(Işık University Press, 2020)In this study, we define the concept of fuzzy parameterized fuzzy soft matrices (fpfs-matrices) and present some of their basic properties. By using fpfs-matrices, we then suggest a new algorithm, i.e. Prevalence Effect ... -
On zagreb indices of double vertex graphs
(Işık University Press, 2020)Let G = (V, E) be a graph with at least 2 vertices, then the double vertex graph U?(G) is the graph whose vertex set consists of all 2-subsets of V such that two distinct vertices {x, y} and {u, v} are adjacent if and only ... -
Eccentricity based topological indices of some graphs
(Işık University Press, 2020)Topological indices are real numbers that are presented as graph parameters introduced during studies conducted on the molecular graphs in chemistry and can describe some physical and chemical properties of molecules. In ... -
Some parameters of the identity graph of multigroup
(Işık University Press, 2020)B. Sharada et. al. [17], have introduced the concept of the identity graph of a multigroup ?(G, E), which derived a representation of the multigroup as a graph. In this paper, we study some parameters of ?(G, E). -
A geometrical study of wang-chen system in view of KCC theory
(Işık University Press, 2020)The present paper discuss the stability of Wang-Chen system from the approach of KCC theory. we show that the system is Jacobi unstable for any value of parameter where as it is linear stable for some choosen parameter. ... -
Some quadratic transformations motivated by the work of kummer and their generalizations
(Işık University Press, 2020)In this paper, we construct two quadratic transformations influenced by the work of Kummer and application of hypergeometric summation theorems of argument “two”. Further, we establish some generalizations of these quadratic ... -
On a new class of integrals involving generalized hypergeometric function ?F?

Generalized lorentz group of space-time transformations
(Işık University Press, 2020)We examine how Lorentz Symmetry (LS) breaks down in Yarman-Arik-Kholmetskii (YARK) theory of gravitation through an entirely different mechanism than that under metric theories of gravity. Said mechanism can be right away ... -
